I am learning STM32MP157A-DK1 according to the 'STM32 MPU wiki by ST' getting started steps, but I found that the IP query command didn't work like the tutorial say:**************** Tutorial ********************Board $> ip addr show eth0 ...
Hi,I'm playing around initramfs shell using initramfs-framework in Yocto environment.I found that the chip abruptly reboots after some time (I think it's around 30 seconds) if the initramfs doesn't fully boot the system by entering systemd.I think it...

If it is possible is there an example or at least some guidance on how to implement the PPS output? Coming from Cortex-M4/RTOS development I am doing my best to learn Application Processor/Embedded Linux development.
Hey everyone,I am working on STM32MP157-DK1 with trustzone cortex-A.I want to use SPI in secure side, but it's possible only with SPI6 that is not mapped to the outside.It's possible to activate SPI (1 ... 5) peripherals in secure side ? if not, why ...
Hello.I want to use MCU (Cortex M4 core) as PMU for MPU (Cortex A7 core).Is it possible to use it in this way?For this I need the following:It's better to start MCU firmware from another source (not SRAM) - from non-volatile memory. Is it possible?Sw...
I already tried the site of st wiki. I only want to get to run the starter package for my work at the university. I saw that you can flash the sd-card wit windows-os. Is that right?I did it with CubeMxProgrammer. And the terminal said programming was...
In RM it is stated that in Engineering mode (BOOT pins at 3'b100) the MPU re-opens CA7 secure debug.I boot in that mode, then halt in openocd:stm32mp15x.cpu0: hardware has 6 breakpoints, 4 watchpoints > halt stm32mp15x.cpu0 rev 5, partnum c07, arch f...
